Report #67716

[architecture] Deadlocks caused by synchronous RPC calls between agents

Design inter-agent communication as asynchronous event-driven messaging \(publish/subscribe or message queues\) rather than synchronous blocking RPC calls.

Journey Context:
Synchronous RPC in multi-agent systems creates temporal coupling. If Agent A calls Agent B and waits, and B calls A \(or just takes 60 seconds\), A hangs, leading to cascading timeouts and deadlocks. Asynchronous queues decouple execution lifecycles: Agent A emits an event and moves on, while Agent B processes it when ready, ensuring system resilience.
